Typically, samples are collected from multiple organs and body fluids after several time-points post administration of the compound. As experts in qPCR analyses, we understand that RNA or DNA extraction from these samples is a very crucial step in the process, since they will be used for highly sensitive molecular testings. Therefore, the risk of contamination has to be minimized by working under the most stringent conditions. Real-Time qPCR data is generated using e.g. TaqMan or SYBR Green chemistry on the ViiA7 instrument (Life Technologies) or digital PCR on the QX200 Droplet Digital PCR System (Bio-Rad). The entire study may be carried out in compliance with GLP.

Looking for In Vivo?

The in vivo part of a preclinical biodistribution study at IMGM can be performed by our strategic partner LPT in Hamburg, Germany, in various model organisms.

Contents of a biodistribution study at IMGM

Our expert team has long-standing experience in complex qPCR assay design and validation, resulting in high-quality data that can be used for determination of:

Limit of detection and quantification

Sensitivity and selectivity
